When we study history, we read the accounts of primitive and superstitious groups getting whipped up and persecuting individuals for failing to adequately conform to the dogma. The Inquisition, the Salem Witch Trials, and so on. We on the one hand ridicule such primitive thinking, and on the other marvel at how much more enlightened our contemporaries supposedly are. Why, it's hard to imagine that people ever behaved that way, we say. Of course, this disbelief is merely the bias that assumes "right now" is always more advanced than "back then".
Look back at the witch hunts, it's astonishing how similar these global warming radicals are. Every new bit of empirical data that undermines their claims simply causes them to double-down, rather than to stand back and reassess their assumptions. That's a sure sign of totally irrational people.
Even if you accepted the premise that global warming is real and that it is due to human activity, people like this guy are still detached from reality. "'They broke the climate. Why should the rest of us have to pay for it?'" So, what, the Steve Zwicks of the world had nothing to do with it then? They never turned on the lights or drove a car? Never used heat or air conditioning? Never ate anything from a grocery store? Ah, of course not. They're the paragons of virtue! The Left has to always define some faultless, noble, victim class, lionize them, then contrast them with the targeted group. It's a way of dehumanizing the people they intend to put into unmarked graves, not for themselves mind you (because they are amoral psychopaths who don't care either way), but for the benefit of the useful idiots from which they intend to build an army.
